I have a Panasonic Lumix FZ72 - not supported
I have a Fuji HS50EXR - not supported
I have converted the RAW files from both cameras into DNG files and now the converted Fuji open but the converted Lumix still won't. Aperture still won't open even DNG files!
I am in the same boat - for my Lumix FZ 28 has not been a raw support since 3 years, but for the Lumix FZ 50 since day one. Aperture has always supported only a subset of cameras that are most likely to be used by professionals.
I have been using dng's for the FZ 28 without problem until a few month ago. Adobe's dng converter used to work very well with the raw format, and Aperture could open those files, but since the last dng converter update this no longer works for the FZ 28. The dngs I created earlier are fine. So this is due to a change in dng converter and not in aperture's raw support.
Aperture's raw support page says:
Aperture works with most DNG files generated from cameras that support this format and with DNG files generated by the Adobe DNG Converter with the “Convert to Linear Image” option turned off.
I have tried all availabe export options in dng converter, and none of the files are excepted by Aperture. So I am working with tiffs right now.
